来源：ACS PublicationsThe electrochemical production of hydrogen peroxide (H2O2) through the two-electron oxygen reduction reaction (2e– ORR) is a sustainable and practical approach that enables efficient on-site generation and represents an extremely promising strategy for environmentally friendly production. Herein, we synthesized a Bidoped CeO2 (Bi0.1Ce0.9O2) catalyst via a one-step hydrothermal in situ self-assembly method. Both synchrotron radiation X-ray diffraction (SR-XRD) and theoretical calculation analysis demonstrate that Bi doping induces lattice expansion in CeO2 and generates Ce/Bi...

来源：ACS PublicationsCerium copper oxytelluride (CCOT) and lanthanum copper oxytelluride (LCOT) nanomaterials have been synthesized through a straightforward hydrothermal route to explore their potential applications in broadband photodetection and nonlinear optical (NLO) devices. Structural and morphological studies confirmed the successful synthesis of phase-pure, uniformly dispersed nanostructures. The indirect band gaps observed by UV–vis diffuse reflectance spectra (DRS) at 4.06 and 4.07 eV for CCOT and LCOT, respectively, in the visible range. Defect-assisted recombination was studied usin...

来源：ACS PublicationsFor next-generation applications, recent developments in sensor fabrication technologies and innovative materials have rendered improved temporal response and spectral detection capabilities feasible. This work demonstrates a dual-mode sensor for simultaneous light and temperature detection. Vacuum thermal evaporation was used to deposit nanostructured polycrystalline TeO2–Li2O–ZnO–Nb2O5–Dy2O3 (TLZND) thin films (∼32 nm crystallites) on monolithic substrates. Field-emission scanning electron microscopy revealed surface morphology and roughness, while Fourier transform infrar...

来源：ACS PublicationsRare-earth oxide-supported Ru metal catalysts are promising for NH3 synthesis owing to a strong metal–support interaction. Modifying rare-earth oxides with a second metal offers an effective approach to tuning support properties, while systematic support engineering to enhance NH3 synthesis performance remains scarce. In this work, a series of Ru/Ce1–aLaaOx catalysts with varying Ce-to-La molar ratios were synthesized and evaluated for NH3 synthesis. The NH3 synthesis rate of Ru/Ce1–aLaaOx exhibits a volcano relationship with an increase in the La content. The optimal Ru/Ce0...
